Definitions
- the present disclosure relates to a device and a method for sorting out fine particles from a particle mixture arranged on a surface of a support element.
- Recycled PET plastic bottles are frequently used in the drink industry for producing new plastic bottles.
- the recycled old bottles are first shredded and then foreign particles, for example, particles of foreign plastics such as PVC, are sorted out from the ground material flow gained in this way.
- the PET particles or PET flakes obtained in this way are then used to manufacture new PET bottles.
- NIR sorter near-infrared sorter
- the ground material flow normally also comprises small foreign particles, however, which are not detected by the optical or NIR sorter. These fine particles can crystallize out during the further processing and so cloud the plastic bottles manufactured from the recycled material.
- an aspect of the present disclosure is to provide a device and method which allow improved sorting out of the fine particles from a ground material flow.
- the method according to the disclosure for sorting out fine particles from a particle mixture arranged on a surface of a support element, whereby the particle mixture comprises particles of different sizes, in particular fine particles with a diameter of up to 1.00 mm, is provided in that the fine particles are at least partially sorted out from the particle mixture by means of an electrostatically charged separating element.
- the fine particles are normally particularly strongly electrostatically charged due to friction, they can be sorted out from the particle mixture by means of the electrostatically charged separating element in a simple manner.

- the separating element can be moved along above the surface of the support element on which the particle mixture is arranged, and in the process sort out the fine particles.
- the support element can be moved in such a way that the particle mixture separates at least partially from the surface of the support element.
- the charged fine particles can be more easily moved by the electric force action to the separating element and settled on this.
- the movement of the support element can particularly comprise shaking, teetering and/or oscillating of the support element.
- the support element can vibrate, particularly at a predetermined frequency.
- the separating element can be electrostatically charged by means of a charging device.
- the separating element can be held at a predetermined potential by means of the charging device.
- the charging device can, for example, be a ribbon generator or Van-de-Graaff generator.
- Fine particles that stick to the separating element can be removed from the separating element.
- the fine particles can be removed away from the particle mixture. This makes it possible to permanently free the particle mixture of the fine particles.
- the separating element can comprise a film or a film roll.
- the film can be moved on the film roll and be freed of the fine particles away from the particle mixture.
- the disclosure furthermore provides a device for sorting out fine particles from a particle mixture that comprises particles of different sizes, in particular fine particles with a diameter of up to 1.00 mm, wherein the device comprises a support element for arranging the particle mixture on a surface of the support element and an electrostatically charged separating element that is formed and/or arranged in such a way that the fine particles can be at least partially sorted out from the particle mixture by means of the electrostatically charged separating element.

- FIG. 1 A side-view of an exemplary device for sorting out fine particles from a particle mixture
- FIG. 2 A side-view of a further exemplary device for sorting out fine particles from a particle mixture
- FIG. 3 A side-view of a further exemplary device for sorting out fine particles from a particle mixture.
- FIG. 1 shows an exemplary support element 101 , whereby a particle mixture 103 is arranged on a surface 102 of the support element 101 .
- the particle mixture comprises particles of different sizes, in particular particles with a maximum diameter of up to 3.0 cm. Particles with a maximum diameter of up to 1.00 mm are designated here as fine particles.
- the particle mixture 103 comprises particles of PET as well as fine particles 104 of foreign plastics, such as PVC.

- the conveyor element is furthermore deflected perpendicularly to the surface 202 , as indicated by the double-sided arrow in FIG. 2 .
- the particle mixture 203 is swirled up, meaning at least partially separated from the surface 202 .
- Due to the lower mass of the fine particles 204 these are more strongly swirled up, meaning they are more strongly separated from the surface 202 .

- the fine particles 304 removed from the film 306 can be caught in a collecting element 310 and fed to a means of disposal.
- the film 306 freed of tine particles 304 is moved farther after the cleaning element 309 , until it is arranged at least partially above the particle mixture 303 and can attract and settle new fine particles 304 .
- the exemplary device can furthermore comprise a charging device, for example, a ribbon generator, which electrostatically charges the film 306 of the separating element 305 , meaning the generator places the separating element under a voltage.
